How much RAM does Medusa need?

Plan on 2–4 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Medusa plus your other workloads fit in RAM with room to spare.

Commerce

A headless commerce backend you own.

A Node-based commerce engine with an API-first design, ready for custom storefronts.

Medusa suits developers who want to build a bespoke storefront on a commerce core they control.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Node.js + PostgreSQL + Redis.
3
Deploy the application
Follow the project’s official install guide for your distribution.
4
Enable HTTPS
Serve it on your own domain behind a reverse proxy with a certificate.
5
Back it up
Schedule a database dump plus a copy of any uploaded files to an off-box location.

Give Medusa its own database user with rights only on its own schema.
Reverse-proxy Medusa and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep Medusa patched — most self-hosting incidents are unpatched software.
